. I I 7 Claims.

This invention relates to the art of preparing bread dough and has particular reference to a machine for automatically measuring and-form'- ing the dough into loaves of various sizes, such as disclosed in Patent Number 2,276,545, dated March 17, 1942.

The invention resides in improvements to that machine and one of the objects of the invention is to provide an automatic dusting mechanism intended to keep all parts of the machine, with which the dough comes in contact, dusted :with flour or other dustingmedium to the end that the dough will not stick or cling to the machine while it is being formed into loaves.

Another obj ect of the invention is the provision of a dusting device of the character referred to, which is automaticin operation and which is provided with means to cause intermittent functioning of certainof its'parts.

A further object of the invention'is the provision of a-loaf' forming'machine which is provided with means to automatically control the feeding mechanism inthe event of an overload.

A further object of the invention is the provision of aloaf forming machine'which is constructed and arranged in such manner that the change over from certain types of forming and cutting rolls to other types may be easily efiected. Another object of the invention is the provision of a device of'the character referred to which is constructed'and arranged so that certain rollers may be moved into and out of dusting position.

The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawings in which:

of the machine illus' anism removed and other parts broken away to illustrate the relation of certain parts.

Fig. 8 is a fragmentarytop plan view of the left side of the machine as illustrated in Fig. 7.

Referring now more particularly to the drawings it will'be understood that in the embodiment herein disclosed my improved machine consists of frame members I0, II, I2,: I3, I4, and I5 which are secured together by any suitable means such as welding or the like. The members Iltto I4 (Fig. 4) are tied together by means of a bed plate I IA. The members ID to I5 inclusive, comprising the frameof the machine are supported by-legs I6, and other legs not shown. The working parts of the machine are supported by the framework as hereinafter described.

The working parts of the machine, for the sake of clarity,'may be divided into the following general mechanisms-namely; driving mechanism,

the feeding mechanism, the dusting mechanism, and the forming mechanism.

The driving mechanism will include the motor or motors, gears, chains, rollers; belts and the like through which motive power is transmitted.

The feeding mechanism will include the several conveyer belts, rollers, and the like which are employed to advance the movement of thedough into and out of the machine.

The dusting mechanism will include all of the elements utilized in storing and transporting the flour or other dusting medium to the various working parts of the machine.

The forming mechanism will include theseveral pairs of rollers used for flattening, cutting, and forming the dough into loaves.

The motive'power of the driving mechanism stems from the primary motor I! which is supported by any suitable means to one of the legs I6 of the framework. I 1

The motive power is transmitted from the motor I! to the various working parts through chains and gear trains more particularly described as follows:

The motor I! (Figs. 2, 5, 6) is provided. with a shaft I8 to which is secured a sprocket I9, over which passes the chain 20, which in turn drives the sprockets ZI, 22, and 23. The sprocket 2| is secured to the shaft 2IA which supports and drives the roller 24 (Fig. 6), which in turn carries the belt 25, which conveys the dough from the machine after it has been formed as hereinafter described.

The sprocket 22, drives the shaft. 22A (Figs. 5

and 6) to. which is secured the pinion 223 which chine illustrated in Fig. 1 with the dusting mechmeshes with the gear 26, thellatterbeing secured i journaledin :oillessibearings. The axlesssuppo'rts :zingz. the rolis 33 andi 42C. are-.ajournaied iin'zmemhinlthe:membersJIiandJL I to the shaft 26A which in turn the forming rolls 21.

The sprocket 23 is secured to the shaft 23A which carries the small roll 28 the latter serving as a filler roll to convey the dough from the forming roll 21 to the conveyor belt 25.

The shaft 26A, at the end opposite the gear 26, carries a gear 29 (Figs. 7 and 8) which in turn meshes with a gear 30 carried on the shaft 3| which supports the roll 32.which is immediately below the roll 21. The 'rolls '2! and '32 are counter parts and make up one of the pairs supports one of of forming rolls. The other pairs consist of theflattening rolls 33 (Fig. 1), and the cutting rolls 34. Power is transmitted from theshaft 3l' to the sprocket 35 (Fig. and throughlthechain 36 to the sprockets 31 and 38, which are respectively mounted on the shafts MAandluAwhich support the filler roll 39 (Fig. 6) and the lower. roll of the pair of rolls 34. On the shaft 34A (Fig..7),.at the end'oppositecthechain.3B,-.is a

gear 40 which meshes with :a .gear.4I carried on the shaft '.4IA which in turn supports \the upper roll-of the.pair.';34.

A pinion 42 (Fig.'7-) carried on ashaft 42A meshes with the gear '40eandrwith fthe gear 43 which is secured to the shaft 43A which in'turn supports the lower roll .of the.pair33. Thegear 43 also meshes with .the gear which drives the shaft 44A which in turn supports-theupper cs0 roll of the pair-33.

The axles supporting the rolls 21, 34, and 38 and their counter parts are journaled in shiftable members 54 which are adapted to slide vertically in channel members 55, which are secured by any suitable means to the side members II and I4. The members 54 are provided with racks 55 (Figs. 2 and 5) which engage pinions 53B carried on the shaft 58, which is rotated by the crank 58A, so that the members 54 may be raised .and lowered.

These rolls are intended to have diflerent -shapesand configurations so that diiferent size and shaped-loaves can be formed. These rolls can be lowered into the positions assumed by the 10118321, 34;. and.3 3, and when so lowered will function and operate in exactly the same manner as 'hereinabove described with reference to rolls 2I,-.34"and;39: -.Whernthemolls z-issus and'oss :areso ilowered'ithe-v rolls 21; 134, .andrzu :are .also lowered to an out-.ofioperatiompnsition below the frame. vz-Stops M: on ithermembersriltlimit itheir :movement.
